[QUOTE="tom m., post: 394384, member: 14956"] kirby, my reamer has a .311 freebore. it puts the new pressure ring on the 300 hybrid just above the neck shoulder junction. i would call compression at about 109.50grns. witch is cool because i hit sticky bolt lift at 108.50gns, at a velocity of 3,056. i liked the 107.5 at 3,037ave and 11 e.s., now i will go tune seating depth at long range. i was amazed, i thought my ohler was broke, so i borrowed my friends ohler and it said the same thing...and on the same day, an extremely hot load of h1000 was doing 2,960, witch is what it should have been. the thing just became a whole new caliber, now i have to get my fingers on some of that new rl-50, haha. *note, if i was to design a reamer from the ground up for this bullet, i might go around .300-.305 freebore. this would/should put the pressure ring right down at the junction, and still leave boiler room. keep in mind, my chambering/rifle may be totally different than someone elses. please use caution, but if you can fit 6-8 grains more than your current retumbo load, then it might be worth a peek. tom [/QUOTE]
